Effective interactions for the configurations 3d44p +3d34s4p + 3d24s24p in the first spectrum of vanadium

Abstract

Energy levels and Lande g-factors for the configurations 3d44p + 3d34s4p + 3d24s24p in the first spectra of vanadium were calculated and compared with experimental values. The calculations were clone in intermediate coupling taking into account explicitly the interactions between configurations, as well as complete effective interactions of the core, and effective interactions dp.Due to the insertion of the various effective interactions and a successful starting point based on a general treatment of the odd configurations in the first spectra of the iron group, there was excellent agreement between the experimental and calculated values.On fitting 233 levels using 28 free interaction parameters a mean error of only 133 cm−1 was obtained, i.e., about 0.4% average difference between the experimental and calculated levels. All the 438 predicted levels were calculated.The experimental and calculated g-factors corresponded very closely.
